Hi Uawci,

Indeed the provided information is not enough for us to determine what exactly causes the reported error. A possible cause could be an old version of the Internationalization package or Scheduler package. Please update the kendo packages to the latest version in order to benefit from the latest bug fixes and features:

It is possible that npm has cached locally some packages including the above mentioned. Try clearing your npm cache, and removing your package-lock.json and node_modules folder and then explicitly running the following command:

• npm i @progress/kendo-angular-scheduler@latest
• npm i @progress/kendo-angular-intl@latest

Then restore the rest of your dependencies with:

• npm i

In case the issue persists, could you provide a StackBlitz or runnable example that reproduces the error, so that we can inspect the code and try to find the root of the issue. Thank you in advance.

hello, thank you for your answer.  when i update the scheduler i get the following error;

 

ERROR in node_modules/@progress/kendo-angular-scheduler/dist/es2015/pdf/pdf-command.directive.d.ts(30,22): error TS2415: Class 'PDFCommandDirective' incorrectly extends base class 'ButtonDirective'.
  Types of property 'onClick' are incompatible.
    Type '(e: any) => void' is not assignable to type '() => void'.

 

due to this error, i have to downgrade the scheduler version.

Hi Uawci,

Indeed, there was an issue caused by the latest version of the Buttons package that led to conflicting names when buttons are used within the Scheduler. We addressed it immediately and released in 1.1.2 version of the Scheduler package that contains the fix:

Upgrading to the latest Scheduler version should resolve the problem.

Remove your package-lock.json and node_modules folder and then explicitly running the following command:

npm i @progress/kendo-angular-scheduler@latest

Then restore the rest of your dependencies with:

npm i

Let me know how it goes.
